Q:Is it necessary to use the rubber tyred roller to crush the upper layer of the asphalt concrete pavement?
The asphalt aggregate ratio and slag amount is more than 6% SMA can not use leather wheel, this is the result of the test section, the rub mastic floating that the depth of the surface structure reduces in this case leather wheel, skid resistance is reduced, skin wheel function is rubbing that is dense, so more suitable for dense graded mixture.
Q:Where is the driving wheel of the steel roller?
Full hydraulic drive, stepless speed change, eighth generation hydraulic single drive single steel wheel roller (SSR200AC-8)
Q:How heavy is the biggest roller?
We used the largest roller weight 33 tons, and then there is no reproduction, upgraded version is not clear
Q:Which is more, domestic or imported rollers?,
Imported rollers are too expensive. Personal advice or choice of domestic, cost-effective, especially the domestic technology is also very advanced, and the gap between foreign countries is not high, cost-effective.
Q:Basic parameters of YZ22G vibratory roller
C stands for codeIn other words, the car has undergone three improvements in A, B, and C.Some enterprises use C to represent the phonetic abbreviations of the series of serial CompactorsBut in order to have very few 20 ton double steel vibratory rollers, the possibility of C in YZ20C represents several generations of products
Q:Where are the rollers attached to the rollers?
There are three. The exact location is as follows:The steel wheel driving speed reducer addition: two is 90 degrees, and put the oil nut, screw it loose, start the engine running, one oil discharge outlet vertical reducer gear oil released after walking again, the two oil outlet of a vertical and a horizontal from the beginning, at the top of the filler filling gear oil, until the level direction of the oil port gear oil out of date. Refueling capacity of about 4.5L.Vibration wheel gear oil additive: three a 120 degree uniform oil adding and discharging port, oil discharge method ibid, to a vertical oil port down oil, after the oil discharge screw on a rotating steel wheel nut, make an oil outlet straight up, another loose oil the mouth slanting down (because the three port is 120 degrees), from the oil filling port gear oil, until the oil port oblique gear oil out of date. Refueling capacity of about 11.5L.After oil addition: gear reducer bridge observation hole loosen nut central, loosen the direction by the reducer and put the oil nut oil (rear axle oil adding and discharging nut good judgment, nut at the top of a concave circular), and then go nuts loosen upper, middle gear oil to observe the outflow of oil can. Refueling capacity of about 18L.
Q:How to choose a second-hand roller?
Roller is an indispensable road equipment in modern road construction. It is widely used in filling and compacting operations of large scale projects such as highways, railways, airports, runways, dams and stadiums. Compared with the new machine of second-hand roller with good price, steel in the world will give you a brief introduction about, how to buy second-hand roller.First, the use of time is a key factor in determining the price of used rollersTreatment of rollers and other construction machinery, although our country does not have the same as the mandatory scrapping of the car, according to the annual use of 2000 hours to calculate, roller service life is generally 10 years. Due to the new roller, the normal use of the case, five years without heavy repair, the machine during this period generally has a good cost performance. The price of used rollers is usually depreciated by 20% in the first year, and then decreased by 5% each year to calculate the basic price. First year depreciation 20%, second year depreciation 15%, third year depreciation 10%, fourth year depreciation 5%. Fifth years after the machine parts, with normal wear and aging, plus some unpredictable factors, the probability is greatly increased when the need to overhaul the roller prices in general, because of the individual machine product phase is different, there are great differences. After 10 years, the roller, with the impact of technology and other factors, the price is generally maintained at 20% below the price of new machines.
Q:How about mountain road roller
Well, I have several friends to buy the mountain road roller is Shantui bulldozers can, nothing else, Shantui roller faults, the cab is too small, no foot throttle roller, the rest of the brand are a foot throttle a hand throttle, Shantui gear is convenient. Variable magnetic valve gear selector is convenient, easy, not a bad five thousand or six thousand, also love the bad, there are disadvantages you strong,

If the change of inflation pressure can change the ground pressure, the range of pressure regulation is 0.11 ~ 1.05 mpa. The tire roller adopts hydraulic, hydraulic or mechanical transmission system, single shaft or full axle drive, wide base tire, articulated frame structure, three point support.
Q:Two grade engineer in Municipal Engineering: what does the wheel overlap overlap?
But in order to better connect the two, the road safe covers the edge just pressed back. If the width of the edge is 30cm, then the 30 cm is the width of the wheel trace overlap. The width of the trip back and forth pressure is 5.7m. I don't know. Do you understand? I feel like this.
